| (54) | Using hardware to double the X-dimension in a video frame |
| (57) The present invention is directed to the use of a specific hardware configuration
in a stand-alone camera 100 for decreasing bus bandwidth. In a preferred embodiment,
an image capture device 1 captures an original amount of image data. Thereafter, a
first image transformation module 18, 19, 20 reduces the original amount of image
data in one dimension, resulting in reduced data. In a most preferred embodiment,
such first image transformation module halves the X-dimension of the image data. The
reduced image data is then communicated across the camera's system bus 6, thus requiring
less bandwidth of such bus. Before displaying the image data on a display 14, 16,
a second image transformation module 17 receives the reduced image data from the system
bus and scales the data back to the original amount, thereby providing sufficient
image data for a display by reducing one dimension of the image data to be communicated
across the camera's system bus and then sealing the reduced image data up to provide
a sufficient amount of data for a display. |
